Stress state around imperfections in welded joints
(Institut za ispitivanje materijala, Beograd, 2015)
Because of their geometry, welded joints can cause a local increase of stress. In the presence of imperfections in welded joints the local stress additionally increases and can lead to the formation of cracks. Cracks are ...
Influence of multiple defects in welded joints subjected to fatigue loading according to sist en iso 5817: 2014
(Institut za ispitivanje materijala, Beograd, 2018)
Structural integrity of pressure vessels is of great importance in ensuring their safe exploitation. Due to this, a number of standards are developed in order to define the criteria according to which materials, technologies ...
